Application filed December22, 1921. Serial No. 524,170.

To all whom it'may concern.

Be it known that I, Gnonc-n Eowane min, a citizenof the United States ofAmerica, and resident of Johannesburg, Transvaal Province, Union ofSouth Africa, have invented certain new and useful Improvements in Pumpsor Pumping Apparatus, of which the following is a specificas tion.

This invention relates to pumps or pumping apparatus and has for itsobject to construct an efiicient pump or pumping apparatus in a simpleand inexpensive manner.

The invention comprises an arrangement in which a plurality of suctionpumps'are employed co-operatively combined with a common suction pipeand a common delivery pipe andactuated by the same actuating means, andadmitting of the efiicient oper--- ation of the pumps with short stroke.

The invention will be fully described in connection with'theaccompanying drawings wherein I illustrate a ment of the invention. 57 YFig. 1 is a part sectional elevation of the arrangement.

Fig. 2 is a sectional plan of Fig. 1 on line a;a0.

Fig. 3 is a sectional plan of Fig. 1 on line y'y and Fig. 1 is asectional plan of Fig. 1 on line ze.

In accordance with the invention I employ a pipe ortubular casing 1which constitutes a common suction pipe for the barrels 2, 3, of the twopumps shown.

The lower pump is positioned in the suction pipe 1 and is surrounded bythe lower portion 1 of the delivery pipe 5, and the upper pump ispositioned in the delivery pipe 5 above the upper end of the suctionpipe 1, communication being established between the suction pipe 1 andthe underside of the valve 6 of said upperpump. The driving means forthe various pumps is located in the common delivery pipe 5.

Although I show the arrangement including two pumps and theirco-operating parts, it is to be understood that any desirednumber ofpumps may be employed disposed one above the other and co-operating witheach other as hereinafter explained.

The lower end of the upper pump barrel 2 is screwed into a part orcasting 7 which is constructed to form a seating 8 for the acomparatively practical embodi-' upper pump valve 6. is pieceyscrewed,

into the'casting 7 above the seating 8 which serves as a stop for thevalve 6'in an upward direction and provides passages 10 for the water topass through on the upstroke of the bucket 11 or equivalent part of thepump, 12 being a suitable lifting'valvej provided in the bucket 11. IThe casting 7 -'s constructed with a flange 13 which is screw-threadedexterio'r'ly' to re;

'ceive the upper end of the common suction ,pipe 1.. The casting 7seeFigs. 2 and 3'is,

constructed with a lateral passagel l which communicates withthem'underside ofzthe valve 6 so that the water is free to pass from theinterior ofthe common suction pipe 1 through said latter passage 1 1 andpastithe "valve 6 into the barrel 2 on the up str'oke of the bucket '11.The, liquid which enters the" pump barrel 2 on the up-stroke'o-fthebucket'f."

'11. passes throughthe valve 12 onthe down- .which stroke stroke of thebucket 11 during the valve 6is closed.

The upper end of thelower portion set the deliverypipeo is screwed intothe casting 7 at 15, and the casting? 'isconstructed to providecommunication between the upper end of the lower portion 4: of thedelivery pipe 5, and the portion of the delivery pipe 5 above thecasting 7.

A part similar to the casting 7, but with- I out the flange 13, will beprovided for each pump between the uppermost and lowermost pumps.

The lower end of the barrel 3 of the lowermost pump has screw-threadedconnection with a casting 16 which is constructed to provide a seating17 for a valve 18; 19 being the stop screwed into the casting 16 for thevalve 18. The lower end of the lower portion 4 of the delivery pipe 5has screw-threaded connection with the casting 16 at 20. The bucket orequivalent 21 of the lower pump is fitted with lifting valve 22 andoperates on its up stroke to draw the liquid from the common suctionpipe 1 through the valve 18into the barrel 3;the liquid passing throughthe valve 22 on the down-stroke of the bucket and the valve 18 remainingclosed. As shown in Fig. 4, the casting 16 may be constructed exteriorlywith ribs 16 which serve to maintain the casting 16 central of thesuction pipe 1 whilst providing free passage for the liquid up thesuction pipe 1 to the uppermost and any intervening pumps.

to the, bucket of 'theother and, as shown,

lowermost pump.

As will be understood, when the pump rod;

23 is lifted the pump buckets 11, 21, are moved through the up-strokeand the water above them thereby raised up to the common delivery pipe5.

The lower end of the suction pipe 1 is positioned in the well or sumpfrom which the liquidis to be pumped and, as shown, it is preferablyfitted withv a rose 29 in which is housed a plurality ofvalves 30; 31being a grid fixed above and serving as a stop to limit the lift of thevalves30.

\Vhat I claim as my invention'and desire to protect by Letters Patentis 1. Pumping apparatus comprising, in combination, 'a plurality ofsuperimposed pumps, a common suction pipe, a common delivery pipeenclosing all the barrels oi saidpuinps, the delivery pipe beingconstructed in sections, and a. part connecting theupper end of thesuction pipe to the sec tion of the delivery pipe of the uppermostp,um,p, said part also carrying the barrel and the valve for theuppermost pump and providing a passage from the common suction pipe tothe underside of the valve and a further passage between the adjacentsections of the delivery pipe/ 2. Pumping apparatus comprising, incombination, a plurality of superimposed pumps, a common suction pipe, acommon delivery pipe enclosing all the barrels of said pumps, thedelivery pipe being constructed in sections, a part connecting the upperend of the suction pipe to the section of the delivery pipe of theuppermost pump, said part alsocarrying the barrel and the valve for theuppermost pump and providing a passage from the common suction pipe tothe underside of the valve and a further passage between the adjacentsections of the delivery pipe, and a common driving means for actuatingall of said pumps, said driv-,

ing means comprising a rod attached to the,

bucket of the uppermost pump, a yoke fixed to said rod, long a furtherrod attached to the bucket of the other pump, and a further yoke fixedto said last-mentioned rod, said further yoke being connected to the rodof the uppermost pump by the long bolts.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
